A blown power valve richens the mixture unbelievable !!
And if you can read boost I'm sure you can read vacuum to verify thAt you have the proper one in!

Pete, I checked and I had 18 in's of vacuum at the manifold at 800 rpm. I was going to try an 8.5 PV in there because right now I have a 4.5 PV. I didn't check the PV that's in there presently to see if it's NG. Is there a way to check it with the motor running? At this point, I think I'll wait to get the exhaust sealed up before I do anymore testing so I know what's going on.
Thanks, Joe
